Esta dissertação analisa a representação direta voluntária a partir de três âmbitos: (i) histórico, (ii) estrutural e (iii) econômico. O perfil histórico é abordado a partir de uma breve construção historiográfica do desenvolvimento da representação desde o período clássico romano, passando pela Idade Média e suas transmutações, com concessões ao brocardo romano alteri stipulari nemo potest, até a construção proposta pela pandectística germânica na figura de Laband. A construção labandiana, lapidada por Hupka, é analisada, posteriormente, sob a perspectiva civilista atual, retomando algumas propostas do modelo idealizado por Laband-Hupka e algumas críticas a este modelo, trazendo como ponto central a questão da abstração da representação em relação ao contrato de mandato e outras figuras gestórias. A figura representativa é, então, colocada sob análise econômica, sob a lupa da Análise Econômica do Direito. A análise ultrapassa a questão de economia de custos que a representação oferece, e que é de meridiana clareza, para analisar, sob a perspectiva da Teoria de Agência e da Teoria de Custos de Transação, os custos gerados por esta figura na negociação e conclusão de contratos / This dissertation analyzes the direct and voluntary representation from three different scopes: (i) historical, (ii) structural, and (iii) economical. The historic profile is broached from a brief historiographical construction of the development of representation from tha classical Roman period, through the Middle Ages and its transmutations, with concessions made to the Roman maxim alteri stipulari nemo potest, until the construction proposed by German Pandect author, Laband. The Laband construction, improved by Hupka, is analyzed, subsequently, under the present civil perspective, retaking some of the proposals of the model idealized by Laband-Hupka and some criticism to this model, bringing as central point of discussion the abstraction of representations towards the contract of mandate and other management relationships. The representative figure is, then, put under economical analysis, under the magnifying glass of Law and Economics. The analysis exceeds the matter of economy of costs that is offered by representation, and which is rather explicit, to analyze, under the perspective of the Agency Theorie and the Costs of Transaction Theorie, the costs generated by this figure in transaction and closing of contracts

For over two hundred years, Chinese immigrants have brought ancient customs and musical traditions to their new homes in America. As in many immigrant communities, a new heritage that embodies and exhibits both the quintessential features of American culture and genuine Chinese heritage have come together to form new expressive cultures that are uniquely "Chinese American." As the youngest of the major American Chinese immigrant centers, the city of Houston, Texas provides an exemplary example of a distinct cultural cohesion that, in part, resulted from significant cultural and political upheavals in the latter half of the twentieth century. During this era of political unrest, many Chinese people's attitudes towards their traditional culture changed drastically. The Houston Chinese Traditional Music Group (HCTMG) is a Chinese orchestra comprised of amateur and professional musicians ranging in age from 13 to over 60 years old. Performing regularly for the Chinese immigrant population in Houston, HCTMG's take on traditional Chinese music deviates greatly from that of older, more established immigrant communities on the East and West Coasts and in some parts of mainland China. Via participant observation, interviews, and analysis of source materials, this paper examines how changing political and economic climates in China during the 1960s to the 1990s—when the majority of HCTMG musicians lived in China –are reflected in the musical decisions of HCTMG and the greater Houston Chinese immigrant community at large.

Contemporary professional violinists face constant exposure to multicultural compositions. For best results, they should be able to understand, capture, and express the subtleties of different styles. The violin and its repertoire spread to China through European missionaries during the late seventeenth century and continued to be developed by Chinese scientists and musicians who studied abroad. During the twentieth and twenty-first centuries, Chinese composers wrote many violin pieces inspired by the unique sounds of Chinese instruments. Additionally, Chinese music scholars wrote numerous essays to discuss the new Chinese style. However, much of this research has been focused on the composers and the structures of the compositions rather than on the details of violin techniques necessary to play the repertoire. The techniques in Chinese violin compositions are unique and are influenced by the traditional instruments including string, wind, and percussion instruments. Furthermore, the style of such compositions is affected by the elements of Chinese culture, such as the language, the elite society and its poetic tradition, and historical legends and events. This dissertation provides examples of Chinese violin repertoire which demonstrate the principles of three main violin techniques in the Chinese style: slides, chords, and pizzicati. In order to help professional violinists better perform Chinese violin compositions, the dissertation also includes a number of exercises covering each technique above.

The modern piccolo trumpet is required by professional trumpet players for the performance of solo repertoire, chamber music, orchestra, and wind band. Students in universities around the world study the piccolo trumpet in preparation for professional careers, but relatively few pedagogical tools exist to specifically focus on the nuanced techniques of the instrument such as articulation, range, and sound production. The purpose of this project is to create a pedagogical guide that can serve as a method for students learning the modern piccolo trumpet.

This study is an historical-philosophical analysis of art education in elementary, secondary, and normal schools in the United States from 1883 to 1910 as revealed through the Journal of Proceedings and Addresses of the National Education Association. Its purposes are to define and describe the role, practices, and status of art education as related to or influenced by selected philosophies, psychologies, theories of learning, and research, along with other prevalent factors such as the scientific, industrial movements, and mores of the period. Art education was found in an admitted state of infancy as the period began. 1883 marked its initial separation from the Manual Training Department and first recognition as an entity. This study of its status traces growth and improvement to a point of tentative public acceptance, and re-attachment of the Art Department to the Manual Training Department as an equal partner. Evidence presented seemed to indicate that progress had been made by art education in several important ways. School administrators had recognized that art did have a legitimate role in education, and a national organization had been formed to act as a forum. A uniform course of study had been presented, and current research in mental development had been considered. The scope of art instruction had been broadened to better serve educational and practical needs. Facilities had been improved, and there was a growing number of trained teachers and supervisors.

The four-valve automatic compensating system as developed by David James Blaikley has become an integral part of the professional euphonium in use today. While the Blaikley system was designed to allow a euphonium to play chromatically down to the fundamental pitch of the instrument, it was hardly the only design to do so. Using a historical analysis of euphonium valve systems, the case is made for why Blaikley's design has been widely adopted in the face of criticism about the four-valve automatic compensating system. The analysis also clarifies the viability of Blaikley's, as well as others', euphonium valve system designs based upon the four factors of intonation, range, intuitiveness of use, and weight. These factors are further explored in a rubric in order to quantify the results of the analysis.

Water management is facing a growing number of challenges in many river basins worldwide, as the equal distribution of the available water resources is increasingly influenced by several, uncertain climatic and anthropic pressures. Within the current and projected water scarcity and drought scenario, such issue represents even a greater challenge in those basins that have been massively regulated in the XX century, as water managers are asked to find balanced policies to stay ahead with multiple, interdependent and ever-increasing water-related requirements. In this context, water conflict has become a recurring problem, with the freshwater ecosystems becoming the sole providers of unbearable human water needs and experiencing a severe alteration of their natural renewability and ecological integrity. In fact, the concern of sustaining the freshwater ecosystems has evolved throughout the years, coming to the fore since the 1990s under the concept of "ecosystem services", defined as the multiple benefits that people obtain from ecosystems. With a high number of challenges still ahead for implementing such paradigm in real-world water management practices, few investigations inspect the long-term evolution of highly regulated basins, being vulnerable freshwater systems characterized by a profusion of ecosystem services in a context of complex management policies and changing anthropic and climatic pressures. We focus our attention on the highly interconnected Garda-Mincio system (Northern Italy), further broadening the results to the regulated basins of the European perialpine region. First, to examine the modification of the freshwater systems from their pristine to their regulated conditions, we carried out an extensive collection of daily hydro-meteorological data by consulting public online sources as well as digitizing historical data contained in hand-written documents. The resulting database, which represents a valuable source of long-term daily hydro-meteorological data for the Garda-Mincio system, additionally underscored the complexity of constructing and maintaining a consistent and up-to-date database within an inter-regional context. The collected data were then adopted to investigate the climatic and anthropogenic drivers that have progressively influenced water availability, the provision of the changing water demands and the trade-offs with the existing water ecosystem services over the last two centuries. Statistical analyses were performed to outline the evolution of the annual and seasonal trends of Lake Garda water levels and outflows over the period 1888-2020, discussing the role of the Salionze Dam operational rules (completed in 1951) as well as the influence of the main water needs of the downstream Mincio River basin (i.e. hydropower production, irrigation and fluvial ecosystem sustenance). The role of hydro-meteorological factors was assessed by implementing a water balance model for Lake Garda, the largest lake in Italy, over the period 1928-2020, performing uncertainty and sensitivity analyses on specific water balance components (i.e. over-lake evaporation and basin evapotranspiration). We then focus our analyses on the management of the hydraulic infrastructures that regulate the first and highly water-stressed stretch of the Mincio River downstream Lake Garda, i.e. the Salionze Dam and the Pozzolo-Marenghello infrastructures, where both high and low flow conditions reveal the inability of the current operational rules to support the new variety of water abstractions while maintaining appropriate environmental flow conditions and flood protection. These analyses were carried out through in-situ measurements and numerical simulations, updating the aging rating curves of the existing hydraulic infrastructures. Drawing on the Garda-Mincio system, we inspected the evolution of the freshwater regimes within the European perialpine lakes framework, discussing the outcomes to describe which common factors drove management policies in the area. Eventually, we discuss our outcomes recommending future sustainable and adaptive water management policies in the area.

The aim of this thesis is to historize discourses of parenthood by analyzing how they are negotiated and legitimized in Swedish non-literary and wide spread texts published in the 1870s, 1940s and 2010s. The analyzed corpus consists of the following: family and women’s movement magazines from the 1870s; a public counseling brochure and weekly magazines from the 1940s; blog texts; online health counseling; parent magazines; and public welfare information from the 2010s. The study moreover aims to make an inventory of which visual and lexico-grammatical resources realize legitimating strategies in the texts. Theoretically, the thesis draws on constructivist and feminist discourse theories and social semiotics. There is an emphasis on subject positions and power relations. The thesis investigates which parental subject positions are legitimized in the corpus, what power relations they reproduce, and furthermore how different positions are transformed as discontinuities of each other and over time. The results are presented in four analytical chapters. In the first of these, findings derived from the legitimation analysis of the 1870s are presented. The following two chapters present the results derived from the analysis of the 1940s and 2010s. The fourth research chapter presents an inventory of semiotic resources with the potential to realize legitimating strategies. One crucial discourse-historical result regards how the position of the mother as primary caretaker predominates in the research data. However, the position is mainly legitimized during the 1870s and transformed into legitimacy during the 1940s and 2010s. The analysis furthermore captures how the same position is legitimized during the 1870s with reference to a discourse concerning a divine order of things. Although this divine discourse is muted during the 1940s and 2010s, it continues to imprint the representations. Moreover, the analysis captures how discourses of legitimate parenthood constitute discourses of manhood, Swedishness, expert knowledge, responsiveness to children, consumption and risk management throughout the investigated periods, yet in discontinuous ways. The overall conclusion drawn is that legitimized discourses from one historical setting can constitute silent foundations for representations in later historical contexts. By unraveling history from past to present, the thesis shows how it is possible to identify presupposed lineages of today’s ideas and discourses, and thereby to deconstruct hegemonic truths and the power relations they reproduce.

The dissertation explores the roles of buildings in urban social life. Buildings, as both a methodological tool and a research site, are valuable for understanding society. As a method, buildings allow access to various urban contexts. As a research site, the material and the social are integrated, where buildings and society are shown in continual construction. The overarching case shows how a new building type is born in a society and what buildings do, as both materiality and meaning, to help bring about outcomes. The study follows a single building type through history and analytical levels in the city of Santiago, Chile where three empirical studies emerge. The first traces a process of late 19th century urbanization to show the entrance of new residential building types into a city and how the physical and social landscape is reshaped in the process, emphasizing how one urban form emerges and is defined. Intercontinental connections bring new architecture and new language, stabilizing the link between form and name in the city. The resulting spectrum of buildings within the type shows how the diversity of residents shapes material outcomes. As the new buildings become fixed in the urban landscape, so too do social categories. How buildings change definitions both between and within societies, as well as start to take on meanings, is explored. Once definitions and form are established, the following studies explore the roles of the buildings in contemporary urban life. Photos analysis is employed to examine uses of shared space (a patio) in a residential building where buildings are theorized as material structures that contribute to patterned activities. It addresses how the building creates opportunities for observed everyday uses of private collective space. Using published comparison cases demonstrates that practices appear to differ between buildings of the same type when income of residents differs. It is hypothesized that opportunity is created not by the existence of the space per se, but by its gated enclosure, which separates the public street from the private space. The building is understood as a bound that simultaneously fosters interaction and exclusion. In addition, activities in these spaces, over time, contribute to new cultural understandings of the building type, showing how use can generate meaning. The last empirical study examines the reuse of residential buildings for commercial purposes in one neighborhood. The goal is to illuminate roles buildings play in contemporary neighborhood transformations. Rather than understanding transformation through reuse itself, modes of material conversions are examined. The differences between older conversions and newer ones in the area highlight the role of visible characteristics in the newly reused buildings. The material maintenance of residential facades on new conversions locks in the visual of a residential neighborhood, where intended function is built into form, even under commercial reuse. This is valuable in line with a constructed narrative about the place that focuses on the past. The building type under investigation is further redefined as reused buildings take on visual and spatial similarities to housing models from a past era that were not involved in changes in the neighborhood, but appear as if they were. This study relies on participant observation and analysis of marketing materials, as well as other documentary sources.

De nombreux domaines d'applications utilisent des représentations spatiales. C'est le cas de l'architecture, de l'urbanisme ou de la géographie. L'acquisition de ces données spatiales en urbanisme a connu ces dernières années des progrès significatifs grâce à l'introduction de nouveaux instruments de mesure. Ces derniers permettent d'obtenir des supports d'analyse urbaine à différents niveaux de détails et pour différentes finalités. Cette thèse propose une approche permettant de combiner deux disciplines, la typo-morphologie urbaine et la géomatique. Nous avons expliqué la notion centrale de processus morphologique, les différentes étapes d'opération propre à l'analyse historique, notamment le traitement des sources cartographiques avec l'outil S.I.G. Notre travail a avant tout consisté à explorer l'apport des S.I.G. au traitement et à l'analyse des données historiques. Nous nous sommes intéressés particulièrement à l'approche typo-morphologique pour compléter le potentiel interprétatif et descriptif. Notre travail de thèse est issu de différentes étapes, nous pouvons mentionner la construction d'une classification formelle, des concepts liés à l'évolution historique et morphologique des villes de Constantine et d'Aix-en-Provence. En partant de cette histoire urbaine, comparer ces deux villes à permis d'établir une chronologie de l'évolution des formes urbaines, de mieux saisir les enjeux de chacune de celles-ci. / Many fields of applications use spatial representations. This is the case of architecture, town planning or geography. The acquisition of these spatial datas in town planning these last years has experienced a significant progress with the introduction of new instruments. This acquisition allows to get urban support analysis at different levels of details and for different purposes. This thesis proposes an approach to combine two disciplines, the urban typomorphology and geomatics. We have explained the central notion of morphological process, the different steps of operation peculiar to the historical analysis for the treatment of map datas with the GIS instrument, primarily our work consist to explore the GIS contribution to the historical data treatment and analysis. We focused particularly on the approach to complete typomorphological potential interpretive and descriptive. Our thesis work has been made from different stages, we can mention the construction of a formal classification, concepts related to the historical development and morphology of Constantine and Aix-en-Provence. Starting from this urban history compare the two cities has established a chronology of the evolution of urban forms, to better understand the challenges each of these latter. Specifically, this work allows us to contribute to improving the mastery of the urban project. Finally tracks are proposed to continue this work by exploiting the platform exploration of 3D representation proved very useful for making historical analysis.
